This invention aims to provide a simple three-piece wrench embodyingnovel means for holding the movable jaw in'adjusted positions withrespect to the fixed jaw.

Figure 1 is a side elevation; Figure 2 is an elevation wherein thewrench is viewed edge,- wise; Figure 3 is a section showing one side ofthe movable jaw; Figure 4 is a section showing the opposite side of themovable jaw;

Figure 5 is a sectionon the line 55 '01: Fig

ure 1; and Figure 6 in a section on the line G6 of Figure 1. In all theviews, parts of Y The wrench includes a body 1, made up of a handle'2,an enlarged head 3 on the handle,

and a fixed jaw 4: on the head. There is a slot 5 in the head, acrosswhich the aw 4 extends, the jaw serving as a connection betweensidewings 6 and 7 that are formed byrthe slot 5. On the inner surface of theflange 6 ,there is a guide groove 8. The flanges 6 and 7 have lines ofcoaxial holes '9, the lines of holes'being parallel to the groove 8. Theflange 7 has an off-set external lip 10 defining an elongated seat 11,the lip and the seat being disposed parallel to the guide groove 8.

The movable jaw is marked by the numeral 12 and has a thinned fin lwhichslides in the slot 5 in the head of the wrench, the fin formingshoulders 15 on each side oft-he tin, the

shoulders sliding on the edges of the flanges I or wings 6 and 7. Thefin 14::has a rib 16' which is received slidably in the guide groove 8.The fin 14 is provided with 'openings 1.7 adapted to register, one at atime, with the I holes 9 in the body of the wrench.

The movable jaw 12 is shifted toward and from the fixed jaw 4:, untilthe required adjustment hasbeenobtained, and then a tapered securingelement (pin) 18 is inserted through the openings 17 and 9 which happentobe alined. The securing element or pin 18 has a handle 19 which swingsparallel to the wing 7, in contactv with, the body 'ofthe wrench. Thehandleis supplied, on opposite sides of the axis of the pin 18, withprojecting fingers 20 which are beveled as shownat 21 to form camswhich, when either one of the fin gers 20 is engaged beneath the liplO,crowd it the tapered pin 18 intolthe holes 17 and 9, to

hold the movablejaw 12 in the position to which it has been adjusted; Itis possible to swing the handle. 19 into such a position that neither ofthe fingers 20 will be engaged under lip 10, and then he pin 18 can beremoved I to permit the movable-jaw 12 to be shifted withrespect tothe'fixed jaw 1-. 'Thereis an advantage in having the duplicated,opposite-.

ly disposed, lingers 20. When the pin. 18 is in a position near totheright hand end-of the line or" holes 9 in Figure 1, one of thefingers 20 may be engaged beneath thelip 10, with, v i

the handle 19 to the left, and when the pin 18 20 can be engaged underthe lip 10, with the is mounted near to the left hand end of the LOW ofholes 9 in Fig 1 the other finger,

handle 19 extending to the ri ht; and in this way, the handle'19fcan beso placed that it will not stick out beyond the edgeoi" the head 3 ofthe wrench. V

Whatis claimed is A wrench the body of which has a fixedjaw v.

and an elongated external lip, a movablejaw cooperating with theflxed awand slidable on the wrench body, the body and a part of the movable awhaving holes adapted to be brought into registration, and a pininsertible into the holes and provided-with a handle, the handle beingprovided oneach side with a finger, either fingerbeingeng'ageableunderthe "vent the handle from projecting beyond til-3" edge of the wrench.when the pin 15; located near to one edge of the wrench,- the edgesotiso 1 lip, to hold the pin in place, the provision of two fingerspermitting the handle .to -be i turned in opposite directions, therebyto pre' the fingers being so inclined with respect to 1 each other thateither finger may be 'disen; f
